The OP may want to look at the main EC261 thread for the various details on this.
If the delay was over 3 hours then the OP is potentially entitled to EC261 Article 7 of up to 600€, unless it was extraordinary circumstances, and we don't have enough detail here on that one.
If the delay was over 5 hours then the OP is entitled to re-routing (as was done) or a partial refund or - and this may be significant - re-routing to a later date. So it may be more sensible to rebook the remaining segments to another travel date if that fits in with the OP's plans, and depending on the cost of TLV-USA for immediate travel. The OP also, incidentally, had the right to a full refund and return to the USA if the purpose of the visit was voided by the delay. The part refund may not be very generous. However all the options here are the customer's choice.
Both the Article 7 and re-routing (etc) can go together, it's not either / or.
But yes, ensure your return is "protected" and I would have thought Twitter can handle this. Shabbat shalom.
